SACRAMENTO, Calif. (AP) -- More than 19.4 million Californians have registered to vote in Tuesday's presidential election, a state record.

Secretary of State Alex Padilla said Friday that about 45 percent are registered Democratic, a slight increase from the last presidential election in 2012. About 26 percent are registered Republican, a slight decrease. Twenty-four percent have no party preference.

The previous voter registration record was set four years ago when nearly 18.25 million people registered to vote. The U.S. Census Bureau says California's population increased by more than one million people from 2012 to 2015.

Padilla says 78 percent of eligible Californians have registered to vote.

That's up about 1 percentage point from 2012. It's the highest percentage of eligible California citizens registered to vote before a general election in 20 years.
